Hello,
 I just noticed that using -Xcompressedrefs causes bad performance issues.
This seems to be related to hotspot compiling. With -Xcompressedrefs my app
takes over 3 minutes to start and after removing only -Xcompressedrefs it
takes 1 minute and 23 seconds to start. So the issue seems to be related to
the flag -Xcompressedrefs.

java version "1.6.0_0"
OpenJDK Runtime Environment (IcedTea6 1.4.1) (6b14-1.4.1-0ubuntu3)
OpenJDK 64-Bit Server VM (build 14.0-b08, mixed mode)


Anyone else noticed something similar?

br,
 Jarkko
